Context
A diagram containing a model, vector database and agent does not explain how a system works. It must show request flow, state ownership, failure recovery, and the points where permissions and data are controlled.
This existing JR Academy book covers 20 topics across platforms and delivery, context and knowledge, runtime and interaction, and trust and governance.
Approach & design
Use different visual forms for different questions: request paths for online calls, state machines for long-running tasks, ingestion/query separation for knowledge systems, and gates and feedback loops for releases. Legends and scenarios define what the arrows mean.
Each topic connects a scenario and its design problem with engineering trade-offs. The complete book retains its references so readers can check the technical basis.
